and agriculturally useful salts thereof.

In addition, the invention relates to processes and intermediates for preparing compounds of the formula I, to compositions comprising them, and to the use of the compounds of the formula I and to compositions comprising them for controlling harmful plants.

2-Benzoylcyclohexane-1,3-diones are disclosed in the literature, for example in EP-A 278 742, EP-A 298 680, EP-A 320 864 and WO 96/14285.

However, the herbicidal properties of the prior art compounds and their crop plant safety are not entirely satisfactory.

It is an object of the present invention to provide novel, in particular herbicidally active, compounds having improved properties.

We have found that this object is achieved by the 2-benzoylcyclohexane-1,3-diones of the formula I and their herbicidal activity.

Furthermore, we have found herbicidal compositions which comprise the compounds I and have very good herbicidal activity. Moreover, we have found processes for preparing these compositions and methods for controlling undesirable vegetation using the compounds I.

The present invention also relates to stereoisomers of the compounds of the formula I. Pure stereoisomers and also mixtures thereof are included.

Depending on the substitution pattern, the compounds of the formula I may contain one or more chiral centers and, if this is the case, are present as mixtures of enantiomers or diastereomers. The present invention relates to both the pure enantiomers or diastereomers and also mixtures thereof.

The compounds of the formula I may also be present in the form of their agriculturally useful salts, the kind of salt generally not being important. The salts of those cations or the acid addition salts of those acids whose cations or anions, respectively, do not adversely affect the herbicidal activity of the compounds I are generally suitable.

Suitable cations are in particular ions of the alkali metals, preferably lithium, sodium and potassium, of the alkaline earth metals, preferably calcium and magnesium, and of the transition metals, preferably manganese, copper, zinc and iron, and also ammonium, where, if desired, one to four hydrogen atoms may be replaced by C₁ -C₄ -alkyl or hydroxy-C₁ -C₄ -alkyl and/or one phenyl or benzyl, preferably diisopropylammonium, tetramethylammonium, tetrabutylammonium, trimethylbenzylammonium, furthermore phosphonium ions, sulfonium ions, preferably tri(C₁ -C₄ -alkyl)sulfonium, and sulfoxonium ions, preferably tri(C₁ -C₄ -alkyl)sulfoxonium.

Anions of useful acid addition salts are primarily chloride, bromide, fluoride, hydrogen sulfate, sulfate, dihydrogen phosphate, hydrogen phosphate, nitrate, hydrogen carbonate, carbonate, hexafluorosilicate, hexafluorophosphate, benzoate and also the anions of C₁ -C₄ -alkanoic acids, preferably formate, acetate, propionate and butyrate.

Emphasis is given to the compounds of the formula I according to the invention where the variable Q is a cyclohexane-1,3-dione ring of the formula IV: ##STR5## which is attached in position 2, where IV also represents the tautomeric formulae IV' and IV": ##STR6## where: R¹¹, R¹², R¹⁴ and R¹⁶ are each hydrogen or C₁ -C₄ -alkyl;

R¹³ is hydrogen, C₁ -C₄ -alkyl or C₃ -C₄ -cycloalkyl, where the last two groups mentioned may carry one to three of the following substituents:

halogen, C₁ -C₄ -alkylthio or C₁ -C₄ -alkoxy;

or

is tetrahydropyran-2-yl, tetrahydropyran-3-yl, tetrahydropyran-4-yl, tetrahydrothiopyran-2-yl, tetrahydrothiopyran-3-yl, tetrahydrothiopyran-4-yl, 1,3-dioxolan-2-yl, 1,3-dioxan-2-yl, 1,3-oxathiolan-2-yl, 1,3-oxathian-2-yl, 1,3-dithiolan-2-yl or 1,3-dithian-2-yl, where the last 6 radicals mentioned may be substituted by one to three C₁ -C₄ -alkyl radicals;

R¹⁵ is hydrogen, C₁ -C₄ -alkyl or C₁ -C₆ -alkoxycarbonyl;

or

R¹³ and R¹⁶ together form a π bond or a three- to six-membered carbocyclic ring;

or

the CR¹³ R¹⁴ unit may be replaced by C═O.

Process A:

Reactions of cyclohexane-1,3-dione [sic] of the formula IV with an activated carboxylic acid Va or a carboxylic acid Vb, which is preferably activated in situ, to give the acylation product VII, and subsequent rearrangement to the compounds of the formula I according to the invention. ##STR7##

L¹ is a nucleophilically exchangeable leaving group such as halogen, for example bromine or chlorine, hetaryl, for example imidazolyl or pyridyl, or carboxylate, for example acetate, trifluoroacetate, ect.

The activated carboxylic acid can be employed directly, as in the case of the acyl halides, or be generated in situ, for example by using dicyclohexylcarbodiimide, triphenylphosphine/azodicarboxylic esters, 2-pyridine disulfite/triphenylphosphine, carbonyldiimidazole, etc.

It may be advantageous to carry out the acylation reaction in the presence of a base. The starting materials and the auxiliary base are advantageously employed in equimolar amounts. A slight excess of the auxiliary base, for example 1.2 to 1.5 molar equivalents, based on II, may be advantageous under certain conditions.

Suitable auxiliary bases are tertiary alkylamines, pyridine or alkali metal carbonates. Examples of solvents which can be used are chlorinated hydrocarbons, such as methylene chloride, 1,2-dichloroethane, aromatic hydrocarbons, such as toluene, xylene, chlorobenzene, ethers, such as diethyl ether, methyl tert-butyl ether, tetrahydrofuran, dioxane, polar aprotic solvents, such as acetonitrile, dimethylformamide, dimethyl sulfoxide, or esters such as ethyl acetate or mixtures of these.

If acyl halides are employed as activated carboxylic acid component, it may be advantageous to cool the reaction mixture to 0-10° C. when adding this reaction partner. The mixture is subsequently stirred at 20-100° C., preferably at 25-50° C., until the reaction is complete. Work-up is carried out in the customary manner, for example by pouring the reaction mixture into water and extracting the product of value. Solvents which are particularly suitable for this purpose are methylene chloride, diethyl ether and ethyl acetate. After the organic phase has been dried and the solvent has been removed, the crude enol ester of the formula VII is purified, preferably by chromatography. Alternatively, it is possible to employ the crude enol ester of the formula VII without further purification for the rearrangement reaction.

The rearrangement of the enol esters of the formula VII to the compounds of the formula I is advantageously carried out at from 20 to 40° C. in a solvent and in the presence of a base and, if appropriate, in the presence of a cyano compound.

Examples of solvents which can be used are acetonitrile, methylene chloride, 1,2-dichloroethane, dioxane, ethyl acetate, toluene or mixtures of these. Preferred solvents are acetonitrile and dioxane.

Suitable bases are tertiary amines such as triethylamine, pyridine or alkali metal carbonates, such as sodium carbonate, potassium carbonate, which are preferably employed in equimolar amounts or up to a four-fold excess, based on the ester. Preference is given to using triethylamine or alkali metal carbonates.

Suitable cyano compounds are inorganic cyanides such as sodium cyanide, potassium cyanide and organic cyano compounds such as acetone cyanohydrin, trimethylsilyl cyanide. They are usually employed in an amount of 1 to 50 mol percent, based on the ester. Preference is given to using acetone cyanohydrin or trimethylsilyl cyanide, for example in an amount of from 5 to 15, preferably 10, mol percent, based on the ester.

Particular preference is given to employing alkali metal carbonates, such as potassium carbonate, in acetonitrile or dioxane.

Work-up can be carried out in a manner known per se. For example, the reaction mixture is acidified with dilute mineral acid, such as 5% strength hydrochloric acid or sulfuric acid, and extracted with an organic solvent, for example methylene chloride, ethyl acetate. The organic extract can be extracted with 5-10% strength alkali metal carbonate solution, for example sodium carbonate or potassium carbonate solution. The aqueous phase is acidified, and the precipitate which forms is filtered off with suction and/or extracted with methylene chloride or ethyl acetate, dried and concentrated.

(Examples of the synthesis of esters of hydroxypyrazoles and the rearrangement reaction of the esters are mentioned for example in EP-A 282 944 or U.S. Pat. No. 4,643,757).

Preference is given to benzoyl halides Va where L=halogen (=V where R¹⁷ =halogen), ##STR10## where the variables R¹, R², and A are each as defined under formula V and

L is halogen, in particular chlorine or bromine.

Preference is also given to benzoic acids of the formula Vb (=V where R¹⁷ =hydroxyl), ##STR11## where where [sic] the variables R¹, R², and A are each as defined under formula V.

Preference is also given to benzoic esters of the formula Vc (=V where R¹⁷ =C₁ -C₆ -alkoxy), ##STR12## where the variables R¹, R², and A are each as defined under formula V and

M is C₁ -C₆ -alkoxy.

The compounds of the formula Va (where L=halogen) can be synthesized by methods similar to those known from the literature (cf. L. G. Fieser, M. Fieser "Reagents for Organic Synthesis", Vol. I, (1967) pp. 767-769) by reacting benzoic acids of the formula Vb with halogenating agents such as thionyl chloride, thionyl bromide, phosgene, diphosgene, triphosgene, oxalyl chloride and oxalyl bromide.

The benzoic acids of the formula Vb can be obtained, inter alia, by hydrolyzing the benzoic esters of the formula Vc (where M=C₁ -C₆ -alkoxy).

The benzoic esters of the formula Vc according to the invention can be synthesized by various methods known from the literature (for example a: G. Dittus in Houben-weyl, Methoden der Organischen Chemie, Volume VI/3, Oxygen Compounds I, 4th Edition, 1965, p. 493 ff., Georg Thieme Verlag; b: T. L. Gilchrist, Heterocyclenchemie, 2nd Edition, Verlag Chemie, 1995), as illustrated in the examples that follow.

Process A

Cyclization of 1,3-halohydrins of the formula VIIIa or VIIIb under alkaline reaction conditions to give the benzoic esters of the formula Vc according to the invention where the variables R¹, R² and M are each as defined under formula V, A is a group of the formula IIa or IIb and L² is a nucleophilically exchangeable leaving group, preferably iodine, bromine or chlorine. ##STR13##

Suitable for use as eliminating agents are especially alkali metal and alkaline earth metal hydroxides, for example potassium hydroxide or sodium hydroxide, or organic bases, for example alkoxides such as sodium methoxide, or secondary amines such as diethylamine.

The elimination of hydrogen halide can be effected even by alkaline salts, for example by potassium fluoride (E. Gryszkiewics-Trochimowski, O. Gryszkiewics-Trochimowski, Bulletin de la Societe Chimique de France, Memoires 123 (1953)).

The cleaving agents may be employed in solution or neat, preferably in solution, for example methanolic sodium methoxide solution.

The cyclization is carried out in inert solvents, for example in alcohols such as methanol or ethanol.

Process B

Photochemical cycloadditions of aldehydes of the formula IX or ketones of the formula X with olefins XI, preferably with enol ethers of the formula XI (where R⁷ =OR¹⁰), to give the benzoic esters of the formula Vc according to the invention where the variables R¹, R², R³, R¹⁰ and M are each as defined under formula V and A is a group of the formula IIa. ##STR14##

The photochemical cycloaddition is carried out in inert solvents which do not have any significant UV absorption in the spectral range used. Thus, for example, acetonitrile or aliphatic or aromatic hydrocarbons such as n-hexane or toluene can be used.

Suitable radiation sources are appropriate UV radiators, preferably low-pressure, medium-pressure or high-pressure mercury lamps (A. M. Braun, M. T. Maurette, E. Oliveros, Photochemical Technology, John Wiley & Sons Ltd 1991). Low-pressure mercury lamps emit at 189 and 253 nm, the emission at 189 nm being almost completely absorbed by oxygen, water or solvent, so that low-pressure mercury lamps virtually emit a monochromatic radiation at 253 nm.

Medium- and high-pressure mercury lamps are operated at pressures from 1 to 100 atm and emit, depending on pressure and temperature, in a wavelength range of from 200 to 600 nm, medium-pressure mercury lamps having a dominant emission line at 366 nm and high-pressure mercury lamps having two dominant emissions at 436 and 546 nm.

Furthermore, it is possible to employ medium- and high-pressure mercury lamps which are doped with metal salts such as thallium halides, indium halides, sodium halides or gallium halides. The doping causes a modification of the emission spectrum of the medium- and high-pressure mercury lamps and results in the emission of additional emission lines characteristic for the doping in question.

In addition, it is possible to use appropriate filters which suppress undesirable wavelength ranges.

Suitable photoreactors should not absorb in the UV range used, but should be transparent for the wavelengths which are emitted by an appropriate UV radiator.

Particularly suitable for this purpose is borosilicate glass, for example borosilicate BK7 (Schott) or Corning 7740 (Pyrex) or quartz glass, which is even more transparent than borosilicate glass in the UV range.

Preferred photoreactors are falling-film reactors.

Process C

Intramolecular cyclization of β-halofatty acids or their alkali metal salts of the formula XIIa or XIIb to give the benzoic esters of the formula Vc according to the invention where the variables R¹, R² and M are each as defined under formula V, A is a group of the formula IIa or IIb and L² is a nucleophilically displaceable leaving group, preferably iodine, bromine or chlorine. ##STR15##

The elimination of hydrogen halide from β-halofatty acids or salts thereof, such as the sodium salts, by aqueous solutions of alkali metal salts, for example sodium carbonate solution, leads to the formation of β-lactones (A. Einhorn, Chem. Ber. 16 (1883), 2208). Instead of sodium carbonate, silver oxide or silver salts are frequently successfully used for the elimination of hydrogen halide.

Owing to the lability of the β-lactones in the presence of aqueous alkali metal halides, it is necessary to prepare water-soluble β-lactones in the presence of solvents to remove the β-lactone formed as quickly as possible from the aqueous phase (Org. Reactions 8 (1954), 309). Suitable solvents include, for example, diethyl ether and chloroform.

Process D

Cycloaddition of aldehydes of the formula IX or ketones of the formula X with ketenes XIII to give the benzoic esters of the formula Vc according to the invention where the variables R¹, R², R³, R⁴, R⁵ and M are each as defined under formula V and A is a group of the formula IIa or IIb. ##STR16##

Depending on the kind of catalyst and the reaction conditions, ketenes react with carbonyl compounds at 20-100° C., preferably at 40-80° C., to form enol acetates or β-lactones (for example H. Kroper in Houben-Weyl, Methoden der Organischen Chemie, Volume VI/2, Oxygen Compounds I, Part 2, 4th Edition, 1965, p. 511 ff., Georg Thieme Verlag). The formation of β-lactones occurs after C-acetylation if basic catalysts such as tertiary amines or alkali metals or alkaline earth metals are employed (J. A. Spence, E. F. Degering, Chem. Abst. 43 (1949), 6654). In the presence of specific catalysts, aldehydes or ketones even condense at lower temperatures of from 0 to 10° C. with the most simple ketenes to form β-lactones. The choice of catalyst depends on the individual carbonyl compounds. Catalysts which are suitable for aromatic aldehydes are, for example, boric acid, triacetyl borate, zinc thiocyanate and zinc chloride, aluminum chloride, mercury(II) chloride, and activated alumina and silica.

The reaction must be carried out in an anhydrous medium in order to achieve high yields.

Suitable for use as solvents are ethers, for example diethyl ether, haloalkanes, for example methylene chloride or chloroform, and, owing to the tendency of the β-lactones to polymerize, preferably ketones.

Process E

Addition of thiol ester enolates XIV to aldehydes of the formula IX or ketones of the formula X by a method similar to processes known from the literature (R. L. Danheiser, J. S. Nowick, Journal of Organic Chemistry 56 (1991), 1176) to give the benzoic esters of the formula Vc according to the invention where the variables R¹, R², R³, R⁴, R⁵ and M are each as defined under formula V and A is a group of the formula IIIa [sic] or IIIb [sic]. ##STR17##

The thiol ester enolates XIV used as starting materials can be prepared in a simple one-step reaction from carboxylic acid derivatives (for example T. Mukaiyama, T. Takeda, K. Atsumi, Chemistry Letters 1974, 187).

The corresponding enolate, which forms the desired compounds of the formula Vc, in particular β-lactones, with aldehydes or ketones, is formed in the presence of an equivalent of a base, preferably a lithium base such as, for example, lithium diisopropylamide.

Process F

Cyclization of 1,2-halohydrins of the formula XVa or XVb under alkaline reaction conditions to give the benzoic esters of the formula Vc according to the invention where the variables R¹, R² and M are each as defined under formula V, A is a group of the formula III and L² is a nucleophilically displaceable leaving group, preferably iodine, bromine or chlorine. ##STR18##

Instead of the 1,2-halohydrins, it is also possible to use their acetates as starting materials in a similar manner.

Related to the methods described is the preparation of benzoic esters of the formula Vc according to the invention by elimination of p-toluenesulfonic acid from 2-hydroxytoluenesulfonates (for example H. Ohle, L. v. Vargha, Chemische Berichte 62, (1929), 2440).

Particularly suitable eliminating agents are alkali metal hydroxides and alkaline earth metal hydroxides; organic bases, for example alkoxides, secondary amines or pyridine and its homologs such as collidine, are less frequently used. Preferred alkali metal hydroxides and alkaline earth metal hydroxides are for example potassium hydroxide, sodium hydroxide or calcium hydroxide.

In some instances, the elimination of hydrogen halide can be effected even by alkaline salts, for example potassium carbonate, barium carbonate or potassium fluoride. Furthermore, the use of aluminates, silicates and zincates (for example J. D. Zech, Chemical Abstracts, 46 (1952), 8672), lead(II) oxide, aluminum oxide, silver nitrate or alkaline ion exchangers has been described.

The cleaving agents can be employed in solution or neat, in some instances in powdered form, for example powdered potassium hydroxide.

Cyclization is carried out in inert solvents. Suitable for this purpose are open-chain or cyclic ethers, for example diethyl ether or dioxane, or aromatic hydrocarbons, for example benzene or toluene.

Process G

Epoxidation of olefins of the formula XVI to give the benzoic esters of the formula Vc according to the invention where the variables R¹, R² and M are each as defined under formula V and A is a group of the formula IIV [sic]. ##STR19##

Similarly to processes known from the literature, the epoxidation is frequently carried out using peracids, for example perbenzoic acid, monoperphthalic acid, performic acid, peracetic acid, trifluoroperacetic acid or perpropionic acid (for example R. Criegee, Houben-Weyl, "Methoden der Organischen Chemie", Volume VIII, Oxygen Compounds III, 4th Edition, 1965, p. 40 ff., Georg Thieme Verlag), hydrogen peroxide or tert-butyl hydroperoxide in alkaline solution, preferably in aqueous sodium hydroxide solution, or using dioxiranes, for example dimethyldioxirane or derivatives thereof such as, for example, (trifluoromethyl)methyldioxirane (W. Adam, A. K. Smerz, Bulletin des Societes Chimiques Belges 105 (1996), 581).

The peracid epoxidation is carried out in inert solvents such as diethyl ether, chloroform, carbon tetrachloride, ethyl chloride or occasionally in glacial acetic acid, whereas dioxiranes are preferably employed in acetone or derivatives thereof such as, for example, trifluoromethyl methyl ketone.

Peracid, hydrogen peroxide, tert-butyl hydroperoxide or dioxirane is often employed for the reaction in a slight excess; however, an excess of olefin may be advantageous if the oxidizing agent is to be utilized fully.

Process H

Condensation of aldehydes of the formula IX with α-halofatty acid esters XVII or related α-halofatty acid derivatives, for example α-halofatty amides, nitriles or ketones in the presence of alkaline condensing agents by processes known from the literature (for example M. Ballester, Chemical Reviews 55 (1955), 283) to give the benzoic esters of the formula Vc according to the invention where the variables R¹, R², R¹⁰ and M are each as defined under formula V and A is a group of the formula III. ##STR20##

Suitable condensing agents are inorganic or organic catalysts, for example sodium hydride in mineral oil, lithium hydride, tetraethylammonium ethoxide, sodium ethoxide, potassium tert-butoxide or diisopropylmagnesium bromide.

The reaction is carried out in inert solvents, for example in xylene, diethyl ether, methanol, ethanol or tert-butanol.

The compounds I and their agriculturally useful salts are suitable, both in the form of isomer mixtures and in the form of the pure isomers, as herbicides. The herbicidal compositions comprising I control vegetation on non-crop areas very efficiently, especially at high rates of application. They act against broad-leaved weeds and grass weeds in crops such as wheat, rice, maize, soybean and cotton without causing any significant damage to the crop plants. This effect is mainly observed at low rates of application.

Depending on the application method used, the compounds I, or the compositions comprising them, can additionally be employed in a further number of crop plants for eliminating undesirable plants. Examples of suitable crops are the following:

Allium cepa, Ananas comosus, Arachis hypogaea, Asparagus officinalis, Beta vulgaris spec. altissima, Beta vulgaris spec. rapa, Brassica napus var. napus, Brassica napus var. napobrassica, Brassica rapa var. silvestris, Camellia sinensis, Carthamus tinctorius, Carya illinoinensis, Citrus limon, Citrus sinensis, Coffea arabica (Coffea canephora, Coffea liberica), Cucumis sativus, Cynodon dactylon, Daucus carota, Elaeis guineensis, Fragaria vesca, Glycine max, Gossypium hirsutum, (Gossypium arboreum, Gossypium herbaceum, Gossypium vitifolium), Helianthus annuus, Hevea brasiliensis, Hordeum vulgare, Humulus lupulus, Ipomoea batatas, Juglans regia, Lens culinaris, Linum usitatissimum, Lycopersicon lycopersicum, Malus spec., Manihot esculenta, Medicago sativa, Musa spec., Nicotiana tabacum (N.rustica), Olea europaea, Oryza sativa, Phaseolus lunatus, Phaseolus vulgaris, Picea abies, Pinus spec., Pisum sativum, Prunus avium, Prunus persica, Pyrus communis, Ribes sylestre [sic], Ricinus communis, Saccharum officinarum, Secale cereale, Solanum tuberosum, Sorghum bicolor (s. vulgare), Theobroma cacao, Trifolium pratense, Triticum aestivum, Triticum durum, Vicia faba, Vitis vinifera and Zea mays.

In addition, the compounds I may also be used in crops which tolerate the action of herbicides owing to breeding, including genetic engineering methods.

The herbicidal compositions or the active compounds can be applied pre- or post-emergence. If the active compounds are less well tolerated by certain crop plants, application techniques may be used in which the herbicidal compositions are sprayed, with the aid of the spraying equipment, in such a way that they come into contact as little as possible, if at all, with the leaves of the sensitive crop plants, while the active compounds reach the leaves of undesirable plants growing underneath, or the bare soil surface (post-directed, lay-by).

The compounds I, or the herbicidal compositions comprising them, can be used for example in the form of ready-to-spray aqueous solutions, powders, suspensions, also highly-concentrated aqueous, oily or other suspensions or dispersions, emulsions, oil dispersions, pastes, dusts, materials for broadcasting, or granules, by means of spraying, atomizing, dusting, broadcasting or watering. The use forms depend on the intended aims; in any case, they should guarantee a very fine distribution of the active compounds according to the invention.

Essentially, suitable inert auxiliaries include: mineral oil fractions of medium to high boiling point, such as kerosene and diesel oil, furthermore coal tar oils and oils of vegetable or animal origin, aliphatic, cyclic and aromatic hydrocarbons, eg. paraffins, tetrahydronaphthalene, alkylated naphthalenes and their derivatives, alkylated benzenes and their derivatives, alcohols such as methanol, ethanol, propanol, butanol and cyclohexanol, ketones such as cyclohexanone, or strongly polar solvents, eg. amines such as N-methylpyrrolidone, and water.

Aqueous use forms can be prepared from emulsion concentrates, suspensions, pastes, wettable powders or water-dispersible granules by adding water. To prepare emulsions, pastes or oil dispersions, the substituted 2-benzoylcyclohexane-1,3-diones, either as such or dissolved in an oil or solvent, can be homogenized in water by means of a wetting agent, tackifier, dispersant or emulsifier. Alternatively, it is possible to prepare concentrates comprising active compound, wetting agent, tackifier, dispersant or emulsifier and, if desired, solvent or oil, which are suitable for dilution with water.

Suitable surfactants are the alkali metal salts, alkaline earth metal salts and ammonium salts of aromatic sulfonic acids, eg. ligno-, phenol-, naphthalene- and dibutylnaphthalenesulfonic acid, and of fatty acids, alkyl- and alkylarylsulfonates, alkyl sulfates, lauryl ether sulfates and fatty alcohol sulfates, and salts of sulfated hexa-, hepta- and octadecanols, and also of fatty alcohol glycol ethers, condensates of sulfonated naphthalene and its derivatives with formaldehyde, condensates of naphthalene, or of the naphthalenesulfonic acids with phenol and formaldehyde, polyoxyethylene octylphenol ether, ethoxylated isooctyl-, octyl- or nonylphenol, alkylphenyl or tributylphenyl polyglycol ether, alkylaryl polyether alcohols, isotridecyl alcohol, fatty alcohol/ethylene oxide condensates, ethoxylated castor oil, polyoxyethylene alkyl ethers or polyoxypropylene alkyl ethers, lauryl alcohol polyglycol ether acetate, sorbitol esters, lignin-sulfite waste liquors or methylcellulose.

Powders, materials for broadcasting and dusts can be prepared by mixing or grinding the active compounds together with a solid carrier.

Granules, eg. coated granules, impregnated granules and homogeneous granules, can be prepared by binding the active compounds to solid carriers. Solid carriers are mineral earths, such as silicas, silica gels, silicates, talc, kaolin, limestone, lime, chalk, bole, loess, clay, dolomite, diatomaceous earth, calcium sulfate, magnesium sulfate, magnesium oxide, ground synthetic materials, fertilizers such as ammonium sulfate, ammonium phosphate and ammonium nitrate, ureas, and products of vegetable origin, such as cereal meal, tree bark meal, wood meal and nutshell meal, cellulose powders, or other solid carriers.

The concentrations of the active compounds I in the ready-to-use preparations can be varied within wide ranges. In general, the formulations comprise from 0.001 to 98% by weight, preferably 0.01 to 95% by weight of at least one active compound. The active compounds are employed in a purity of from 90% to 100%, preferably 90% [sic] to 100% (according to the NMR spectrum). The compounds I according to the invention can be formulated for example as follows:

I 20 parts by weight of the compound No. 110.1 are dissolved in a mixture composed of 80 parts by weight of alkylated benzene, 10 parts by weight of the adduct of 8 to 10 mol of ethylene oxide to 1 mol of oleic acid N-monoethanolamide, 5 parts by weight of calcium dodecylbenzenesulfonate and 5 parts by weight of the adduct of 40 mol of ethylene oxide to 1 mol of castor oil. Pouring the solution into 100,000 parts by weight of water and finely distributing it therein gives an aqueous dispersion which comprises 0.02% by weight of the active compound.

Pouring the solution into 100,000 parts by weight of water and finely distributing it therein gives an aqueous dispersion which comprises 0.02% by weight of the active compound.

III 20 parts by weight of the active compound No. 110.1 are dissolved in a mixture composed of 25 parts by weight of cyclohexanone, 65 parts by weight of a mineral oil fraction of boiling point 210 to 280° C. and 10 parts by weight of the adduct of 40 mol of ethylene oxide to 1 mol of castor oil. Pouring the solution into 100,000 parts by weight of water and finely distributing it therein gives an aqueous dispersion which comprises 0.02% by weight of the active compound.

IV 20 parts by weight of the active compound No. 110.1 are mixed thoroughly with 3 parts by weight of sodium diisobutylnaphthalenesulfonate, 17 parts by weight of the sodium salt of a lignosulfonic acid from a sulfite waste liquor and 60 parts by weight of pulverulent silica gel, and the mixture is ground in a hammer mill. Finely distributing the mixture in 20,000 parts by weight of water gives a spray mixture which comprises 0.1% by weight of the active compound.

V 3 parts by weight of the active compound No. 110.1 are mixed with 97 parts by weight of finely divided kaolin. This gives a dust which comprises 3% by weight of active compound.

VI 20 parts by weight of the active compound No. 110.1 are mixed intimately with 2 parts by weight of calcium dodecylbenzenesulfonate, 8 parts by weight of fatty alcohol polyglycol ether, 2 parts by weight of the sodium salt of a phenol/urea/formaldehyde condensate and 68 parts by weight of a paraffinic mineral oil. This gives a stable oily dispersion.

VII 1 part by weight of the compound No. 110.1 is dissolved in a mixture composed of 70 parts by weight of cyclohexanone, 20 parts by weight of ethoxylated isooctylphenol and 10 parts by weight of ethoxylated castor oil. This gives a stable emulsion concentrate.

VIII 1 part by weight of the compound No. 110.1 is dissolved in a mixture composed of 80 parts by weight of cyclohexanone and 20 parts by weight of Wettol® EM 31 (nonionic emulsifier based on ethoxylated castor oil). This gives a stable emulsion concentrate.

To widen the activity spectrum and to achieve synergistic effects, the substituted 2-benzoylcyclohexane-1,3-diones I may be mixed with a large number of representatives of other herbicidal or growth-regulating active compound groups and then applied concomitantly. Suitable components for mixtures are, for example, 1,2,4-thiadiazoles, 1,3,4-thiadiazoles, amides, aminophosphoric acid and its derivatives, aminotriazoles, anilides, (het)aryloxyalkanoic acids and their derivatives, benzoic acid and its derivatives, benzothiadiazinones, 2-aroyl-1,3-cyclohexanediones, hetarylaryl ketones, benzylisoxazolidinones, meta-CF₃ -phenyl derivatives, carbamates, quinolinecarboxylic acid and its derivatives, chloroacetanilides, cyclohexane-1,3-dione derivatives, diazines, dichloropropionic acid and its derivatives, dihydrobenzofurans, dihydrofuran-3-ones, dinitroanilines, dinitrophenols, diphenyl ethers, dipyridyls, halocarboxylic acids and their derivatives, ureas, 3-phenyluracils, imidazoles, imidazolinones, N-phenyl-3,4,5,6-tetrahydrophthalimides, oxadiazoles, oxiranes, phenols, aryloxy- and hetaryloxyphenoxypropionic esters, phenylacetic acid and its derivatives, phenylpropionic acid and its derivatives, pyrazoles, phenylpyrazoles, pyridazines, pyridinecarboxylic acid and its derivatives, pyrimidyl ethers, sulfonamides, sulfonylureas, triazines, triazinones, triazolinones, triazolecarboxamides and uracils.

It may furthermore be advantageous to apply the compounds I, alone or else concomitantly in combination with other herbicides, even in the form of a mixture with other crop protection agents, for example together with agents for controlling pests or phytopathogenic fungi or bacteria. Also of interest is the miscibility with mineral salt solutions, which are employed for treating nutritional and trace element deficiencies. Non-phytotoxic oils and oil concentrates may also be added.

The active compound application rates are from 0.001 to 3.0, preferably 0.01 to 1.0 kg/ha of active substance (a.s.), depending on the control target, the season, the target plants and the growth stage.

Preparation of the End Products

4-(2',4'-Dichloro-3'-(3"-hydroxy-3"-methyl-2"-oxetanylbenzoyl)-5,5-dimethyl-1,3-cyclohexanedione (compound 110.1)

A solution of 0.8 g (0.003 M [sic]) of 2,4-dichloro-3-(3'-hydroxy-3'-methyl-2'-oxetanyl)benzoic acid, 0,4 g (0,003 M [sic]) of 5,5-dimethyl-1,3-cyclohexanedione and 0.7 g (0.003 M [sic]) of dicyclohexylcarbodiimide in 40 ml of dry acetonitrile was stirred at room temperature for 12 h. The precipitate was then filtered off and the filtrate was then taken up in aqueous potassium carbonate solution. After extraction of the aqueous phase with ethyl acetate, the pH was adjusted to 2 using 10% strength aqueous hydrochloric acid, and the mixture was re-extracted with ethyl acetate. The combined organic phases were washed neutral with water, dried with sodium sulfate and filtered and the solvent was distilled off under reduced pressure. The residue was purified over 50 g of silica gel (0.04-0.06 mm) using mixtures of dichloromethane and methanol of from 100:1 to 10:1 (v/v). 0.2 g of 4-(2',4'-dichloro-3'-(3"-hydroxy-3"-methyl-2"-oxetanylbenzoyl)-5,5-dimethyl-1,3-cyclohexanedione was obtained.

The herbicidal activity of the substituted 2-benzoylcyclohexane-1,3-diones of the formula I was demonstrated by greenhouse experiments:

The culture containers used were plastic pots containing loamy sand with approximately 3.0% of humus as the substrate. The seeds of the test plants were sown separately for each species.

For the pre-emergence treatment, the active compounds, which had been suspended or emulsified in water, were applied directly after sowing by means of finely distributing nozzles. The containers were irrigated gently to promote germination and growth and subsequently covered with translucent plastic hoods until the plants had rooted. This cover caused uniform germination of the test plants, unless this was adversely affected by the active compounds.

For the post-emergence treatment, the test plants were first grown to a height of 3 to 15 cm, depending on the plant habit, and only then treated with the active compounds which had been suspended or emulsified in water. For this purpose, the test plants were either sown directly and grown in the same containers, or they were first grown separately as seedlings and transplanted into the test containers a few days prior to treatment. The application rate for the post-emergence treatment as 0.5 or 0.25 kg/ha of a.s.

Depending on the species, the plants were kept at 10-25° C. or 20-35° C. The test period extended over 2 to 4 weeks. During this time, the plants were tended, and their response to the individual treatments was evaluated.

The evaluation was carried out using a scale from 0 to 100. 100 means no emergence of the plants, or complete destruction of at least the aerial parts, and 0 means no damage, or normal course of growth.

The plants used in the greenhouse experiments belong to the following species:
